As part of Win7 workstation installation I implemented encryption.
The machine is intended to be used Off-line with a local account (no domain validation).
Can I use the local account to validate the workstation encryption in stead of the domain account?
(moved to encryption)
The MDE login is completely separate of any Windows account - though it can share a user name with a Domain account for SSO etc, or you can create a user account in EPO separate from anything.
You can't ever use Windows credentials to login to MDE - you can use MDE creds which are identical though.
I am not familiar with all abbreviations given in your answer.
MDE login = McAfee Drive Encryption login.
SSO = Single Sign On
EPO refers to the ePolicy Orchestrator
If I have read this correctly you are indicating that if I modify the local windows user login to be the same as the MDE login, windows automatically 'adopts' the credentials and will successfully validate on it.
Quite the opposite.
you can never login to mde with windows credentials. You must use mde credentials.
those mat be the same as the windows ones, or they may not. you sen set them up automatically to always be the same using the epo active directory connector and sso features etc, but this does not work, and can not work using local credentials. Windows simply does not support it.
